Apple’s developer beta program has reached the third round, with fresh builds of iOS 26.4, iPadOS 26.4, watchOS 26.4, tvOS 26.4, and visionOS 26.4 testable, but not macOS Tahoe 26.4.

The third developer betas for iOS 26.4, iPadOS 26.4, watchOS 26.4, tvOS 26.4, and visionOS 26.4 arrive after the second, which appeared on February 23. The first round landed on February 16.
However, it’s not a clean sweep of builds, as there’s not a third developer beta for macOS Tahoe 26.4. It could still be introduced at a later point in the coming week.
